Little Ya Wen lives in a shelter with her parents who collect and sell rubbish for money. Her mother Gao explained the little girl was knocked down by a speeding van last year. She was rushed to hospital where doctors managed to stabilise her.
She woke up a week later and recovered fully after a couple of months - but her mum soon found her secretly smoking cigarettes.
And she was soon stealing packs off her father's cigarettes - as well as putting them on their local shop tab. Gao said her daughter has now been addicted to smoking for a year and has also taken a liking to drink and changed her preference in clothes.
"She only likes boy's clothes. If we don't buy them for her, she cries in protest.
"She also likes drinking.
"Three glasses of beer is no problem to her."
